             only displayed when the user is editing the field.  This control is best used for
             small-to-medium sized lists of options that can reasonably be scanned and selected
             in a drop-down control.  If the list of options is managed by ValueSet, the designer
             should be confident that the set of codes will both be fully available and appropriately
             sized.  For larger lists, the autocomplete control is more appropriate.</td>
